Modeling Analysis for Management of Artificial Rechargeby Abnish C. Amar, US Army Corps of Engineers, Los, Angeles, CA, USA,
Abstract: The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting from construction and operation of the proposed Mentone Dam. The modeling analysis includes effects of the dam on historical potentiometric levels and basin storage for water years 1945 through 1980 assuming the dam and sedimentation effects to be in place in 1945. It is found that no effect on groundwater basin storage results from the dam and reservoir area with application of relocated groundwater recharge facilities within project limits. Localized depressions in potentiometric levels in the immediate vicinity of the dam would be accompanied by localized rises in other parts of the groundwater basin as a result of the project.
